What are some accurate comparisons between Mexico's coastal areas and its heartland?

The most striking difference between Mexico's coasts and its heartland is the climate. While most Mexican coasts fall within the so-called "tierra caliente" (warm land) and are considered to have a tropical savanna climate, most of Mexico's interior belongs to the "tierra templada" and "tierra fria" denominations (temperate land and cool land, respectively). This translates into warm, humid coasts with fairly constant temperatures between 24°C (75°F) and 28°C (83°F), and 1,000 millimeters (40 inches) of rainfall in an average year. On the other hand, in the interior you will see highlands with relatively constant, pleasant temperatures throughout the year between 16°C (61°F) and 20°C (68°F). On more northerly locations you will experience sizable seasonal variations. Above 2,000 meters (6,600 feet) of altitude, temperatures drop as low as an average yearly range between 8°C (47°F) and 12°C (54°F).
